Setting jumpers

You can configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electric switch.

It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To

“close” a jumper you connect the pins with the clip. To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3. In this case you would connect either pins

1 and 2 or 2 and 3.

Open Closed Closed 2-3

The jumper settings are schematically depicted in this manual as follows:

1 2 3

Open Closed Closed 2-3

A pair of needle-nose pliers may be helpful when working with jumpers.

If you have any doubts about the best hardware configuration for your application, contact your local distributor or sales representative before you make any changes.


CPU installing and upgrading

You can upgrade to a more powerful Pentium II/III CPU at any time.

Simply remove the old CPU, install the new one, and set the jumpers for the new CPU speed.

Warning! Always disconnect the power cord from your chassis when you are working on it. Do not make connections while the power is on as sensitive electronic components can be damaged by the sudden rush of power. Only experienced electronics personnel should open the PC chassis.

Caution!

Always ground yourself to remove any static charge before touching the PC board. Modern electronic devices are very sensitive to static electric charges. Use a grounding wrist strap at all times. Place all electronic components on a static-dissipative surface or in a static-shielded bag when they are not in the chassis.


Installing DRAM (DIMMs)

System Memory

The left edge of the PCM-6890B contains a socket for 168-pin dual inline memory module (DIMM). The socket uses 3.3 V unbuffered synchronous DRAM (SDRAM). DIMM is available in capacities of

16, 32, 64, 128, or 256 MB. The socket can be filled in the DIMM of any size, giving your PCM-6890B single board computer between

16 and 258 MB of memory.

Supplementary information about DIMM

Your PCM-6890B can accept both regular and PC-100 SDRAM

DIMM Module(with or without parity). However. The PCM-6890B can only accept PC-100 SDRAM Module.

Single-sided modules are typically 16 or 128MB; double-sided modules are usually 32 or 256 MB.

Memory Installation Procedures

To install SDRAM, first make sure the two handles of the SDRAM socket are in the "open" position. i.e. The handles remain outward.

Slowly slide the SDRAM module along the plastic guides on both ends of the socket. Then press the SDRAM module right down into the socket, until you hear a click. This is when the two handles have automatically locked the memory module into the correct position of the SDRAM socket. (See Figure below) To take away the memory module, just push both handles outward, and the memory module will be ejected by the mechanism in the socket.


Cache memory

Since the second level cache has been embedded into the Celeron /

Pentium III CPUs, you do not have to take care of either SRAM chips or SRAM modules. The built-in second level cache in the

Celeron yields much higher performance than the external cache memories. The cache size in the Celeron CPUs is 128 KB, but 256KB for Pentium III CPUs.


Clear CMOS (J1)

You can use J1 to clear the CMOS data if necessary. To reset the

CMOS data, set J1 to 2-3 closed for just a few seconds, and then move the jumper back to 1-2 closed.

IDE hard drive connector (CN6)

You can attach one or two Enhanced Integrated Device Electronics hard disk drives to the mainboard's internal controller. The mainboard's IDE controller uses a PCI local-bus interface. This advanced interface supports faster data transfer and allows the IDE hard drive to exceed 528 MB.

Connecting the hard drive

Connecting drives is done in a daisy-chain fashion and requires one of two cables, depending on the drive size.

Wire number 1 on the cable is normally red or blue, and the other wires are usually gray.

1. Connect one end of the cable to CN6. Make sure that the red

(or blue) wire corresponds to pin 1 on the connector, which is labeled on the board (on the right side).

2. Plug the other end of the cable to the Enhanced IDE hard drive, with pin 1 on the cable corresponding to pin 1 on the hard drives. (see your hard drive's documentation for the location of the connector).

Connect a second drive as described above.

Unlike floppy drives, IDE hard drives can connect to either end of the cable. If you install two drives, you will need to set one as the master and the other one as the slave by using jumpers on the drives. If you install just one drive, set it as the master.

Keyboard and mouse connector

(CN11)

The mainboard provides a keyboard connector which supports both a keyboard and a PS/2 style mouse. In most cases, especially in embedded applications, a keyboard is not used. The standard

PC/AT BIOS will report an error or fail during power-on-self-test

(POST) after a reset if the keyboard is not present. The mainboard BIOS Advanced setup menu allows you to select "Present" or "Absent" under the "System Keyboard" section. This allows no-keyboard operation in embedded system applications without the system halting under POST (power-on-self-test).

Floppy drive connector (CN17)

You can attach up to two floppy drives to the mainboard controller. You can use any combination of 5¼" (360 KB and 1.2 MB) and/or 3½" (720 KB, 1.44 MB, and 2.88 MB) drives.

A 34-pin daisy-chain drive connector cable is required for a dualdrive system. On one end of the cable is a 34-pin flat-cable connector. On the other end are two sets of floppy disk drive connectors. Each set consists of a 34-pin flat-cable connector

(usually used for 3½" drives) and a printed-circuit board connector (usually used for 5¼" drives).

Wire number 1 on the cable is normally red or blue, and the other wires are usually gray.

Connecting the floppy drive

1. Plug the 34-pin flat-cable connector into CN17. Make sure that the red or blue wire corresponds to pin 1 on the connector.

2. Attach the appropriate connector on the other end of the cable to the floppy drive(s). You can use only one connector in the set. The set on the end (after the twist in the cable) connects to the A: drive. The set in the middle connects to the B: drive.

3. If you are connecting a 5¼" floppy drive, line up the slot in the printed circuit board with the blocked-off part of the cable connector.

If you are connecting a 3½" floppy drive, you may have trouble

determining which pin is pin number 1. Look for a number

printed on the circuit board indicating pin number 1. Also,

the connector on the floppy drive connector may have a slot.

When the slot is up, pin number 1 should be on the right.

Check the documentation that came with the drive for more

information.

If you desire, connect the B: drive to the connectors in the

middle of the cable as described above.

DiskOnChip (DOC) 2000 Installation

When the DOC is installed correctly, a DOC will work like an HDD or an FDD. To install the DOC on the mainboard, follow the instructions below:

1. Plug the DOC into the socket. Make sure pin 1 of the DOC is aligned with pin 1 of the socket.

2. Push the DOC into the socket until it is firmly seated in the

socket.

Caution: the DOC may be permanently damage if it is installed incorrectly.

3. Set the jumper for the memory address of the DOC.

Note:

The memory shadow function sometimes will create conflicts with the memory window. You should disable the memory shadow from the BIOS SETUP if the DOC cannot be accessed.

Configure DOC as a boot device

To configure a DOC as a boot drive, you should copy the operating system files onto the DOC. The following procedure is an example of the initialization process.

1. Install a DOC into your system.

2. Insert a bootable floppy disk in drive A: and boot the system.

3. At the DOS prompt, type SYS C: to transfer the DOS system files to the DOC (assuming the DiskOnChip is installed as drive

C:). Reboot the system.

4. Go to the BIOS Setup Utility by hitting the <DEL> key. Set the type of Primary Master or C: Drive as Not Installed.

5. Remove the floppy disk from the drive A: and leave the BIOS

Setup Utility. The system should boot from the DOC.

Award BIOS Setup

This chapter describes how to configure the BIOS for the PCM-6890B.

Chapter 3 Award BIOS Setup 41

Starting setup

The Award BIOS is immediately activated when you first turn on the computer. The BIOS reads system configuration information in

CMOS RAM and begins the process of checking out the system and configuring it through the power-on self test (POST).

When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and hands control of system operations to it.

During POST, you can start the Setup program in one of two ways:

1.By pressing Del immediately after switching the system on, or

2.By pressing Del or pressing Ctrl-Alt-Esc when the following message appears briefly at the bottom of the screen during POST:

TO ENTER SETUP BEFORE BOOT PRESS DEL KEY

If the message disappears before you respond and you still wish to enter Setup, restart the system to try again by turning it OFF then

ON or pressing the RESET button on the system case. You may also restart by simultaneously pressing Ctr-Alt-Del. If you do not press the keys at the correct time and the system does not boot, an error message appears and you are again asked to

PRESS F1 TO CONTINUE, DEL TO ENTER SETUP

Press F1 to pop up a small help window that describes the appropriate keys to use and the possible selections for the highlighted item. To exit the Help Window press Esc or the F1 key again.

In Case of Problems

If, after making and saving system changes with Setup, you discover that your computer no longer is able to boot, the Award-

BIOS supports an override to the CMOS settings that resets your system to its default configuration.

You can invoke this override by immediately pressing Insert; when you restart your computer. You can restart by either using the ON/

OFF switch, the RESET button or by pressing Ctrl-Alt-Delete.

The best advice is to alter only settings that you thoroughly understand. In particular, do not change settings in the Chipset screen without a good reason. The Chipset defaults have been carefully chosen by Award Software or your system manufacturer for the best performance and reliability. Even a seemingly small change to the Chipset setup may causing the system to become unstable.

This standard setup menu allows users to configure system components such as the date, time, hard disk drive, floppy drive, display, and memory. Online help for each field can be accessed by pressing F1.

Date and Time Configuration

The BIOS determines the day of the week from the other date information. This field is for information only.

Press the left or right arrow key to move to the desired field (date, month, year). Press the PgUp/- or PgDn/+ key to increment the setting, or type the desired value into the field.

The time format is based on the 24-hour military-time clock. For example, 1 p.m. is 13:00:00. Press the left or right arrow key to move to the desired field. Press the PgUp/- or PgDn/+ key to increment the setting, or type the desired value into the field.

HARD DISKS

The BIOS supports up to four IDE drives. This section does not show information about other IDE devices, such as a CD-ROM drive, or about other hard drive types, such as SCSI drives.

NOTE: We recommend that you select type AUTO for all drives.

The BIOS can automatically detect the specifications and optimal operating mode of almost all IDE hard drives. When you select type AUTO for a hard drive, the BIOS detects its specifications during POST, every time the system boots.

If you do not want to select drive type AUTO, other methods of


selecting the drive type are available:

1.Match the specifications of your installed IDE hard drive(s) with

the preprogrammed values for drive types 1 through 45.

2.Select USER and enter values into each drive parameter field.

3.Use the IDE HDD AUTO DECTECTION function in Setup.

Here is a brief explanation of drive specifications:

•Type: The BIOS contains a table of pre-defined drive types. Each

defined drive type has a specified number of cylinders,

number of heads, write precompensation factor, landing

zone, and number of sectors. Drives whose specifications

do not accommodate any pre-defined type are classified as

type USER.

•Size: Disk drive capacity (approximate). Note that this size is

usually slightly greater than the size of a formatted disk

given by a disk-checking program.

• Cyls: Number of cylinders

• Head: Number of heads

• Precomp: Write precompensation cylinder

• Landz: Landing zone

• Sector: Number of sectors

• Mode: Auto, Normal, Large, or LBA

- Auto: The BIOS automatically determines the optimal mode.

- Normal: Maximum number of cylinders, heads, and sectors

supported are 1024, 16, and 63.

- Large: For drives that do not support LBA and have more than

1024 cylinders.


- LBA (Logical Block Addressing): During drive accesses, the

IDE controller transforms the data address described by

sector, head, and cylinder number into a physical block

address, significantly improving data transfer rates. For

drives with greater than 1024 cylinders.

Halt On

During the power-on-self-test (POST), the computer stops if the

BIOS detects a hardware error. You can tell the BIOS to ignore certain errors during POST and continue the boot-up process.

These are the selections:

• No errors: POST does not stop for any errors.

• All errors If: the BIOS detects any non-fatal error, POST stops

and prompts you to take corrective action.

• All, But Keyboard: POST does not stop for a keyboard error, but

stops for all other errors

• All, But Diskette: POST does not stop for diskette drive errors,

but stops for all other errors.

• All, But Disk/Key: POST does not stop for a keyboard or disk

error, but stops for all other errors.

Memory

You cannot change any values in the Memory fields; they are only for your information. The fields show the total installed random access memory (RAM) and amounts allocated to base memory, extended memory, and other (high) memory. RAM is counted in kilobytes (KB: approximately one thousand bytes) and megabytes

(MB: approximately one million bytes).

RAM is the computer's working memory, where the computer stores programs and data currently being used, so they are accessible to the CPU. Modern personal computers may contain up to 64 MB, 128 MB, or more.

•

Base Memory

Typically 640 KB. Also called conventional memory. The DOS operating system and conventional applications use this area.


•

Extended Memory

Above the 1-MB boundary. Early IBM personal computers could not use memory above 1 MB, but current PCs and their software can use extended memory.

•

Other Memory

Between 640 KB and 1 MB; often called High memory. DOS may load terminate-and-stay-resident (TSR) programs, such as device drivers, in this area, to free as much conventional memory as possible for applications. Lines in your CONFIG.SYS file that start with LOADHIGH load programs into high memory.


BIOS features setup

By choosing the BIOS FEATURES SETUP option from the INITIAL

SETUP SCREEN menu, the screen below is displayed.


The displayed configuration is based on the manufacturer's SETUP

DEFAULTS settings.

Virus Warning

When enabled, you receive a warning message if a program

(specifically, a virus) attempts to write to the boot sector or the partition table of the hard disk drive. You should then run an antivirus program. Keep in mind that this feature protects only the boot sector, not the entire hard drive.

NOTE: Many disk diagnostic programs that access the boot

sector table can trigger the virus warning message. If you plan to run such a program, we recommend that you first disable the virus warning.

CPU Internal Cache/External Cache

Cache memory is additional memory that is much faster than conventional DRAM (system memory). CPUs from 486-type on up contain internal cache memory, and most, but not all, modern PCs have additional (external) cache memory. When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for even faster access by the CPU.

The External Cache field may not appear if your system does not have external cache memory.

CPU L2 Cache ECC Checking

When you select Enabled, memory checking is enable when the external cache contains ECC SRAMs.

Quick Power On Self Test

Select Enabled to reduce the amount of time required to run the power-on-self-test (POST). A quick POST skips certain steps. We recommend that you normally disable quick POST. Better to find a problem during POST than lose data during your work.


Boot Sequence

The original IBM PCs loaded the DOS operating system from drive

A (floppy disk), so IBM PC-compatible systems are designed to search for an operating system first on drive A, and then on drive C

(hard disk). However, the BIOS now offers many boot sequence options.

Swap Floppy Drive

This field is effective only in systems with two floppy drives.

Selecting enabled assigns physical drive B to logical drive A, and physical drive A to logical drive B.

Boot Up Floppy Seek

When Enabled, the BIOS tests (seeks) floppy drives to determine whether they have 40 or 80 tracks. Only 360-KB floppy drives have

40 tracks; drives with 720 KB, 1.2 MB, and 1.44 MB capacity all have 80 tracks. Because very few modern PCs have 40-track floppy drives, we recommend that you set this field to Disabled to save time.

Boot Up NumLock Status

Toggle between On or Off to control the state of the NumLock key when the system boots. When toggled On, the numeric keypad generates numbers instead of controlling cursor operations.

Gate A20 Option

Gate A20 refers to the way the system addresses memory above 1

MB (extended memory). When set to Fast, the system chipset controls Gate A20. When set to Normal, a pin in the keyboard controller controls Gate A20. Setting Gate A20 to Fast improves system speed, particularly with OS/2 and Windows.

Security Option

If you have set a password, select whether the password is required every time the System boots, or only when you enter

Setup.


Shadow

Software that resides in a read-only memory (ROM) chip on a device is called firmware. The AwardBIOS permits shadowing of firmware such as the system BIOS, video BIOS, and similar operating instructions that come with some expansion peripherals, such as, for example, a SCSI adaptor.

Shadowing copies firmware from ROM into system RAM, where the CPU can read it through the 16-bit or 32-bit DRAM bus.

Firmware not shadowed must be read by the system through the 8bit X-bus. Shadowing improves the performance of the system

BIOS and similar ROM firmware for expansion peripherals, but it also reduces the amount of high memory (640 KB to 1 MB) available for loading device drivers, etc.

Enable shadowing into each section of memory separately. Many system designers hardwire shadowing of the system BIOS and eliminate a System BIOS Shadow option.

Video BIOS shadows into memory area C8000-DFFFF. The remaining areas shown on the BIOS Features Setup screen may be occupied by other expansion card firmware. If an expansion peripheral in your system contains ROM-based firmware, you need to know the address range the ROM occupies to shadow it into the correct area of RAM.


CHIPSET features setup

By choosing the CHIPSET FEATURES SETUP option from the




DEFAULTS settings.

This section allows you to configure the system based on the specific features of the installed chipset. This chipset manages bus speeds and access to system memory resources, such as SDRAM.

It also coordinates communications between the conventional ISA bus and the PCI bus. It must be stated that these items should never need to be altered. The default settings have been chosen because they provide the best operating conditions for your system. The only time you might consider making any changes would be if you discovered that data was being lost while using your system.

Because of the complexity and technical nature of some of the options, not all of the options are described here.

SDRAM RAS-to-CAS Delay

This field lets you control the number of DCLKs between a Row

Activate command and a read or write command.

SDRAM RAS Precharge Time

The precharge time is the number of cycles it takes for the RAS to accumulate its charge before DRAM refresh. If insufficient time is allowed, refresh may be incomplete and the DRAM may fail to retain data. This field applies only if synchronous DRAM is installed in the system.

SDRAM CAS Latency Time

When synchronous DRAM is installed, you can control the number of CLKs between when the SDRAMs sample a read command and when the contoller samples read data from the

SDRAMs. Do not reset this field from the default value specified by the system designer.


SDRAM Precharge Control

When Enabled, all CPU cycles to SDRAM result in an All Banks

Precharge Command on the SDRAM interface.

DRAM Data Integrity Mode

Select Non-ECC or ECC (error-correcting code), according to the type of installed DRAM.

System BIOS Cacheable

Selecting Enabled allows caching of the system BIOS ROM at

F0000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result.

Video BIOS Cacheable

Selecting Enabled allows caching of the video BIOS ROM at

C0000h to C7FFFh, resulting in better video performance. However, if any program writes to this memory area, a system error may result.

Video RAM Cacheable

Selecting Enabled allows caching of the video memory (RAM) at

A0000h to AFFFFh, resulting in better video performance. However, if any program writes to this memory area, a memory access error may result.

8/16 Bit I/O Recovery Time

The I/O recovery mechanism adds bus clock cycles between PCIoriginated I/O cycles to the ISA bus. This delay takes place because the PCI bus is so much faster than the ISA bus.

These two fields let you add recovery time (in bus clock cycles) for

16-bit and 8-bit I/O.


Memory Hole at 15M-16M

You can reserve this area of system memory for ISA adapter ROM.

When this area is reserved, it cannot be cached. The user information of peripherals that need to use this area of system memory usually discusses their memory requirements.

Passive Release

When Enabled, CPU to PCI bus accesses are allowed during passive release. Otherwise, the arbiter only accepts another PCI master access to local DRAM.

Delayed Transaction

The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select Enabled to support compliance with PCI specification version 2.1.

Auto Detect DIMM/PCI Clk

When the Auto Detect DIMM/PCI clk enable, the Utility will automatically detect the DIMM/PCI clock in your system.

Spread Spectrum

When the system clock generator pulses, the extreme values of the pulse generate excess EMI. Enabling pulse spectrum spread modulation changes the extreme values from spikes to flat curves, thus reducing EMI. This benefit may in some cases be outweighed by problems with timing-critical devices, such as a clock-sensitive

SCSI device

IN0-IN6(V)

These fields display the current voltage of up to seven voltage input lines, if your computer contains a monitoring system.


Power management setup

By choosing the POWER MANAGEMENT option from the




DEFAULTS settings.

Power Management

This option allows you to select the type (or degree) of power saving for Doze, Standby, and Suspend modes.

This table describes each power management mode:

Max Saving

User Define

Min Saving

Maximum power savings. Only Available for

SL CPUs. Inactivity period is 1 minute in each mode.

Set each mode individually. Select time-out periods in the section for each mode, below.

Minimum power savings. Inactivity period is

1 hour in each mode (except the hard drive).


PM Control by APM

If Advanced Power Management (APM) is installed on your system, selecting Yes gives better power savings.

Video Off Method

Determines the manner in which the monitor is blanked.

V/H SYNC+Blank System turns off vertical and horizontal synchronization ports and writes blanks to the video buffer.

DPMS Support Select this option if your monitor supports the Display Power Management Signaling

(DPMS) standard of the Video Electronics

Standards Association (VESA). Use the software supplied for your video subsystem to select video power management values.

Blank Screen System only writes blanks to the video buffer.

Video Off After

As the system moves from lesser to greater power-saving modes, select the mode in which you want the monitor to blank.

MODEM Use IRQ

Name the interrupt request (IRQ) line assigned to the modem (if any) on your system. Activity of the selected IRQ always awakens the system.

Doze Mode

After the selected period of system inactivity, the CPU clock throttles to a small percentage of its duty cycle — between 10 percent and 25 percent for most chipsets. All other devices still operate at full speed.


Standby Mode

After the selected period of system inactivity, the CPU clock stops, the hard drive enters an idle state, and the L2 cache enters a powersave mode. All other devices still operate at full speed.

Suspend Mode

After the selected period of system inactivity, the chipset enters a hardware suspend mode, stopping the CPU clock and possibly causing other system devices to enter power management modes.

HDD Power Down

After the selected period of drive inactivity, any system IDE devices compatible with the ATA-2 specification or later power manage themselves, putting themselves into an idle state after the specified timeout and then waking themselves up when accessed.

Throttle Duty Cycle

When the system enters Doze mode, the CPU clock runs only part of the time. You may select the percent of time that the clock runs.

VGA Active Monitor

When Enabled, any video activity restarts the global timer for

Standby mode.

Soft-Off by PWR-BTTN

When you select Instant Off or Delay 4 Sec., turning the system off with the on/off button places the system in a very low-powerusage state, either immediately or after 4 seconds, with only enough circuitry receiving power to detect power button activity or

Resume by Ring activity.

Resume by Ring

When Enabled, an input signal on the serial Ring Indicator (RI) line

(in other words, an incoming call on the modem) awakens the system from a soft off state.


IRQ8 Break [Event From] Suspend

You can select Enabled or Disabled for monitoring of IRQ8 (the

Real Time Clock) so it does not awaken the system from Suspend mode.

Reload Global Timer Events

When Enabled, an event occurring on each device listed below restarts the global timer for Standby mode.

IRQ3-7, 9-15, NMI

Primary IDE 0

Primary IDE 1

Floppy Disk

Serial Port

The Plug and Play AwardBIOS can automatically configure all the boot and Plug and Play-compatible devices. If you select Auto, all the interrupt request (IRQ) and DMA assignment fields disappear, as the BIOS automatically assigns them.

Reset Configuration Data

Normally, you leave this field Disabled. Select Enabled to reset

Extended System Configuration Data (ESCD) when you exit Setup if you have installed a new add-on and the system reconfiguration has caused such a serious conflict that the operating system cannot boot.

IRQ n Assigned to

When resources are controlled manually, assign each system interrupt as one of the following types, depending on the type of device using the interrupt:

Legacy ISA Devices compliant with the original PC AT bus specification, requiring a specific interrupt (such as IRQ4 for serial port 1).

PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for PCI or ISA bus architecture.

DMA n Assigned to

When resources are controlled manually, assign each system DMA channel as one of the following types, depending on the type of device using the interrupt:


Legacy ISA Devices compliant with the original PC AT bus specification, requiring a specific DMA channel

PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for PCI or ISA bus architecture.

PCI IRQ Activated by

Leave the IRQ trigger set at Level unless the PCI device assigned to the interrupt specifies Edge-triggered interrupts.

Assign IRQ for VGA

If you are not using your system's VGA controller, select Disabled to free the IRQ resource.

Used Mem base addr

Select a base address for the memory area used by any peripheral that requires high memory.

Used Mem Length

Select a length for the memory area specified in the previous field.

This field does not appear if no base address is specified.

Assign IRQ for USB

Select Enabled if your system has a USB controller and you have one or more USB devices connected. If you are not using your system’s USB controller, select Disabled to free the IRQ resource.


Load BIOS defaults/Load setup defaults

LOAD BIOS DEFAULTS loads the default system values directly from ROM. The BIOS DEFAULTS provides the most stable settings, though they do not provide optimal performance. LOAD

SETUP DEFAULTS, on the other hand, provides for maximum system performance. If the stored record created by the setup utility becomes corrupted (and therefore unusable), BIOS defaults will load automatically when you turn the PCM-6890 on.


Integrated peripherals setup

By choosing the INTEGRATD PERIPHERALS option from the initial SETUP SCREEN menu, the screen below is displayed.



DEFAULSTS settings.

IDE HDD Block Mode

Select Enabled only if your hard drives support block mode.

IDE PIO Modes (Primary Master/Slave)

The four IDE PIO (Programmed Input/Output) fields let you set a

PIO mode (0-4) for each of up to four IDE devices that the internal

PCI IDE interface supports. Modes 0 through 4 provide successively increased performance. In Auto mode, the system automatically determines the best mode for each device.

IDE Primary Master/Slave UDMA

UDMA (Ultra DMA) is a DMA data transfer protocol that utilizes

ATA commands and the ATA bus to allow DMA commands to transfer data at a maximum burst rate of 33 MB/s. When you select

Auto in the four IDE UDMA fields (for each of up to four IDE devices that the internal PCI IDE interface supports), the system automatically determines the optimal data transfer rate for each IDE device.

On-Chip PCI IDE (Primary)

The Intel 82C440BX chipset contains a PCI IDE interface with support for two IDE channels. Select Enabled to activate the primary and/or secondary IDE interface. Select Disabled to deactivate this interface, if you install a primary and/or secondary add-in

IDE interface.

USB Keyboard Support

Select Enabled if your system contains a Universal Serial Bus

(USB) controller and you have a USB keyboard.


Onboard FDC Controller

Select Enabled if your system has a floppy disk controller (FDC) installed on the system board and you wish to use it. If you install an add-in FDC or the system has no floppy drive, select Disabled in this field.

Consult your IR peripheral documentation to select the correct setting of the TxD and RxD signals.

ECP Mode Use DMA

Select a DMA channel for the port.

EPP Mode select

Select EPP port type 1.7 or 1.9.

Onboard Serial Port 3.

Serial Port 3 Use IRQ.

Onboard Serial Port 4.

Serial Port 4 Use IRQ.


Supervisor/User password setting

You can set either SUPERVISOR or USER PASSWORD, or both of them. The difference between the two is that the supervisor password allows unrestricted access to enter and change the options of the setup menus, while the user password only allows entry to the program, but not modify options.


When you select this function, a message appears at the center of the screen:

ENTER PASSWORD:

Type the password, up to eight characters, and press Enter. Typing a password clears any previously entered password from CMOS memory.

Now the message changes:

CONFIRM PASSWORD:

Again, type the password and press Enter.

To abort the process at any time, press Esc.

In the Security Option item in the BIOS Features Setup screen, select System or Setup:

System Enter a password each time the system boots and when

ever you enter Setup.

Setup Enter a password when ever you enter Setup.

NOTE: To clear the password, simply press Enter when asked to enter a password. Then the password function is disabled.


IDE HDD auto detection

The IDE HDD AUTO DETECTION utility can automatically detect the IDE hard disk installed in your system. You can use it to selfdetect and/or correct the hard disk type configuration. You need to repeat the setup for each of the IDE combinations:


Save & exit setup

If you select this option and press <ENTER>, the values entered in the setup utility will be recorded in the chipset's CMOS memory.

This chapter provides information about:

• Driver types and installation

Chapter 4 Driver Installation 77

Software drivers

This chapter describes the operation and installation of the display drivers supplied on the Supporting CD-ROM that are shipped with your product.

The onboard VGA adapter is based on the CHIPS VGA Flat Panel/CRT controller and is fully IBM VGA compatible. This controller offers a large set of extended functions and higher resolutions. If you intend to use your VGA adapter in standard VGA modes only, you do not need to install any of these drivers. Since your VGA adapter is fully compatible, it does not require any special drivers to operate in standard modes.

The purpose of the enclosed software drivers is to take advantage of the extended features of the CHIPS VGA Flat Panel/CRT controller.

Hardware configuration

Some of the high-resolution drivers provided in this package will work only in certain system configurations. If a driver does not display correctly, try the following:

1. Change the display controller to CRT-only mode, rather than flat panel or simultaneous display mode. Some high-resolution drivers will display correctly only in CRT mode.

2. If a high-resolution mode is not supported on your system, try using a lower-resolution mode. For example, 1024 x 768 mode will not work on some systems, but 800 x 600 mode is supported on most.


Necessary prerequisites

The instructions in this manual assume that you understand elementary concepts of MS-DOS and the IBM Personal Computer. Before you attempt to install any driver from the Supporting CD-ROM, you should:

• Know how to copy files from a CD-ROM to a directory on the hard disk

• Understand the MS-DOS directory structure

If you are uncertain about any of these concepts, please refer to the

DOS or OS/2 user reference guides for more information before you proceed with the installation.

Before you begin

Programming the

Watchdog Timer

A

The mainboard is equipped with a watchdog timer that resets the CPU or generates an interrupt if processing comes to a standstill for whatever reason. This feature ensures system reliability in industrial stand-alone and unmanned environments.

Appendix A Programming the Watchdog Timer 101

Programming the watchdog timer

Watchdog timer

The watchdog timer uses a 8-bit counter. The time range is from 32 seconds to 254.5 min with a resolution of 1 min. When timer times out, a system reset will happen.

Configuration register

The watchdog timer of PCM-6890B is located on the chipset –

Winbond W83977. If you want to use it, you have to know how to read/write the configuration register of W83977. The basic procedure is as follows.

1. Enter configuration mode.

2. Select Logical Device.

3. Select register number.

4. Write/read data to/from register.

5. Exit configuration mode.

To Enter/Exit the configuration mode is to write a specific value to configuration port — 3F1h.

Enter configuration mode: write value 87h to configuration port twice.

Exit configuration mode: write value aah to configuration port.

102 PCM-6890B User Manual

How to set the watchdog timer

1. Set register 30h of logical device 7 to 1 to activate the timer.

2. Write the desired counter value to register F2h of logical deivice

8.

Logical Device 7 : Register number 30h (CR30)

00h : timer inactive

01h : timer active

Logicel Device 8 : Register number F2h (CRF2)

00h : Time-out Disable
